[PATCH] D12695: [Driver] Use UniversalCRT on Windows if available

Fri Sep 11 07:03:35 PDT 2015

Hi İsmail,

Clang tries to detect pathes automatically only if corresponding 
environment variables are not set. In your case, you have these 
variables set, so clang honors them.

You have only set pathes for VC libraries and Universal CRT, but the 
kernel32.lib library is shipped with Windows SDKs and probably located 
at the path like "C:\Program Files (x86)\Windows 
Kits\8.1\Lib\winv6.3\um\x64".
